Hello,

Your question isn't related to Django, so it is not suitable for this group.
You should send questions about App Engine software to an App Engine-related
group.

Having said that, the error message that you are getting is telling you that
your employeekeys list does not contain keys, it contains references to the
key method of each Employee instance in your query resultset.

You need to change the line

employeekeys.append(employee.key)

to

employeekeys.append(employee.key())

Now your list will contain the keys.

Cheers,

Kev
